    // 上传头像

    // 接口文档：https://www.showdoc.com.cn/1834761734600444/8477923164668939


    // 功能列表
    // 功能1: 上传头像
    // 功能2: 页面初始化: 获取个人信息，并渲染到页面中
    // 功能3: 省市区的联动效果
    // 功能4: 保存个人信息，刷新页面，可以看到自己保存的个人信息
    //        说明：由于接口提供的是相同账号下的个人信息，所以当大家都在练习的时候，会出现互相覆盖的情况

    // 要求： 
    // 1. 使用 axios 发送请求
    // 2. 设置 axios 请求根路径
    // 3. 配合 async await 完成功能


    // 根路径
    axios.defaults.baseURL = "http://ajax-api.itheima.net"
